Recent and episodic volcanic and glacial activity on Mars revealed by the High Resolution Stereo Camera

Jaumann, R.; Head, J. W.; Neukum, G. +9 more

The large-area coverage at a resolution of 10-20metres per pixel in colour and three dimensions with the High Resolution Stereo Camera Experiment on the European Space Agency Mars Express Mission has made it possible to study the time-stratigraphic relationships of volcanic and glacial structures in unprecedented detail and give insight into the g…

Perennial water ice identified in the south polar cap of Mars
